Deploy war to WebLogic using Maven

First off you need Maven and Weblogic setup in your computer to start this tutorial.
My Weblogic(10.3.6.0) has setup under : C:\Oracle\Middleware.

Set Middleware home :

 
set MW_HOME=C:\Oracle\Middleware

1. Build the plug-in JAR file using the WebLogic JarBuilder Tool (wljarbuilder) under %MW_HOME%/wlserver_10.3/server/lib/ with the following command:

 
java -jar wljarbuilder.jar -profile weblogic-maven-plugin

The weblogic-maven-plugin.jar contains a Project Object Model (pom.xml) file which specifies the groupId, artifactId, version, and packaging of the weblogic-maven-plugin.jar:
 groupId=com.oracle.weblogic
artifactId=weblogic-maven-plugin
version=10.3.6.0
packaging=maven-plugin

2. Extract the pom.xml file from weblogic-maven-plugin.jar under the %MW_HOME% wlserver_10.3/server/lib directory, and then copy the pom.xml file to %MW_HOME%/wlserver_10.3/server/lib.

 
jar xvf %MW_HOME%/wlserver_10.3/server/lib/weblogic-maven-plugin.jar META-INF/maven/com.oracle.weblogic/weblogic-maven-plugin/pom.xml

copy %MW_HOME%/wlserver_10.3/server/lib/META-INF/maven/com.oracle.weblogic/weblogic-maven-plugin/pom.xml  to %MW_HOME%//wlserver_10.3/server/lib/pom.xml

Add following in your project pom.xml file:


3.Provision the weblogic-maven-plugin.jar in your local Maven repository with the following command. However, for a shortened command-line goal invocation of the plug-in, follow the directions in next step 4 before performing this step.
http://docs.oracle.com/cd/E21764_01/web.1111/e13702/maven_deployer.htm

 
mvn install:install-file -Dfile=%MW_HOME%/wlserver_10.3/server/lib/weblogic-maven-plugin.jar -DpomFile=pom.xml

4.
  you can shorten the full invocation of the plug-in by providing a pom.xml file  and modifying the settings.xml file located in your $HOME/.m2 directory, before you provision the plug-in in your Maven repository

1. Change the settings.xml file as follows:
   

   
   
   
      
      com.oracle.weblogic
    

 b. Replace the %MW_HOME%/wlserver_10.3/server/lib/pom.xml file with the following(Use same version that was in the pom.xml):

  4.0.0
  com.oracle.weblogic
  weblogic-maven-plugin
  maven-plugin
  10.3.4
  Maven Mojo Archetype
  http://maven.apache.org
  
    
      org.apache.maven
      maven-plugin-api
      2.0
    
  
 
  
   
      
       maven-plugin-plugin
       2.3
       
         weblogic
       
      
    
  
 

From within MW_HOME/wlserver_10.3/server/lib/, run the mvn install command.

mvn install

From within MW_HOME/wlserver_10.3/server/lib/, provision the weblogic-maven-plugin.jar in your local Maven repository as follows:

mvn install:install-file -Dfile=%MW_HOME%/wlserver_10.3/server/lib/weblogic-maven-plugin.jar -DpomFile=pom.xml

Now, you can use a shortened command-line goal invocation, such as:

mvn weblogic:deploy

Deployment Goals
weblogic.deploy
weblogic:undeploy
weblogic:redeploy
weblogic:start-app
weblogic:stop-app
weblogic:list-apps
weblogic:update-app
weblogic:help


  

Create Oracle Stored Procedure example

Following is a basic oracle store procedure example:

CREATE OR REPLACE PROCEDURE procPrintHelloWorld
IS

 usr_id VARCHAR2(20):=' sujan ';
BEGIN
 
  DBMS_OUTPUT.PUT_LINE('Hello World!'|| usr_id);
 
END;
/

To see output on console you need to run following command.

 set serveroutput on size 30000;

Run store procedure:

 EXEC procPrintHelloWorld;

If you get any compilation error, run following command to display it.

SHOW ERRORS

Add SVN email notification

SVN email notification is important when many programmer involves  in software development. For example, you are working on module and other programmers are using that. So if you check-in updated the classes , you have to notify other developers that module has been updated.

SVN provide post commit hook option, there you can add any script or programme that would be execute after SVN commit. Here I will add email notification in post-commit hook script.

I have create a repository in /apps/subversion/hsolite/.
Using ls command you can see default directories created under repository. There is a directory called hooks where you will put you post-commit script. When any user will commit in SVN, post-commit script will be execute.

To send email notification you need find out "mailer.py" and "mailer.conf"

[root@domU-12-31-39-09-29-13 hsolite]# find / -name "mailer.py"
/usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/mailer.py

[root@domU-12-31-39-09-29-13 hsolite]#  find / -name "mailer.conf"

/usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/tests/mailer.conf

Now copy the mailer.py and mailer.conf  under /apps/subversion/hsolite/hooks and  /apps/subversion/hsolite/ respectively.

[root@domU-12-31-39-09-29-13 hsolite]#  cp /usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/mailer.py   /apps/subversion/hsolite/hooks/mailer.py

[root@domU-12-31-39-09-29-13 hsolite]# cp  /usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/tests/mailer.conf   /apps/subversion/hsolite//mailer.conf

Now edit the mailer.conf and override following properties

mail_command = /usr/sbin/sendmail

commit_subject_prefix = [svn-myproject]

from_addr = noreply@mydomain.com

to_addr = commits-myproject@mydomain.com  # this is a mailing list

Under hooks directory you will find "post-commit.tmpl" that you need to rename to "post-commit".

Replace "post-commit" script  contains with the following snippet.

------------------------------------------------

#!/bin/sh

REPOS="$1"

REV="$2"

/apps/subversion/hsolite/hooks/mailer.py commit "$REPOS" "$REV" /apps/subversion/hsolite/mailer.conf

-------------------------------------------------------

Make sure "post-commit" is executable.

[root@domU-12-31-39-09-29-13 hsolite]# chmod +x post-commit

Testing :

Using svnlook  yon can get latest revision number.

[root@domU-12-31-39-09-29-13 ~]# svnlook info /apps/subversion/hsolite/

[root@domU-12-31-39-09-29-13 ~]# svnlook youngest /apps/subversion/hsolite/

2850

Test the hook script:

[root@domU-12-31-39-09-29-13 ~]# REPOS=/apps/subversion/hsolite/

[root@domU-12-31-39-09-29-13 ~]#  REV=2850

[root@domU-12-31-39-09-29-13 ~]#  "$REPOS"/hooks/mailer.py commit "$REPOS" $REV "$REPOS"/mailer.conf 

After run above command you should receive email notification with revision number 2850

[root@domU-12-31-39-09-29-13 ~]# REPOS=/apps/subversion/hsolite/
[root@domU-12-31-39-09-29-13 ~]#  REV=2850
[root@domU-12-31-39-09-29-13 ~]#   sh $REPOS/hooks/post-commit  $REPOS$REV

If post-commit script run successfully then commit some files in SVN then check your email inbox for notification.

Weblogic JPA 2.0 configuration

If you find following exception in webloginc while running JPA 2.0 web application
Caused By: java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

you need to add following line in commEnv.cmd( located at %BEA_HOME%\wlserver_10.3\common\bin\) just after  "set BEA_HOME=C:\Oracle\Middleware"


set PRE_CLASSPATH=%BEA_HOME%\modules\javax.persistence_1.1.0.0_2-0.jar;%BEA_HOME%\modules\com.oracle.jpa2support_1.0.0.0_2-1.jar

Then restart your server again.

Increase Weblogic heap size

Go to your domain bin directory and find setDomainEnv.cmd.
For example:
C:\Oracle\Middleware\user_projects\domains\base_domain1\bin\setDomainEnv.cmd.

Open it in any text editor and find following block.  Change -Xms1G -Xmx1G

if "%JAVA_VENDOR%"=="Sun" (
set WLS_MEM_ARGS_64BIT=-Xms1G -Xmx1G
set WLS_MEM_ARGS_32BIT=-Xms1G -Xmx1G
) else (
set WLS_MEM_ARGS_64BIT=-Xms1G -Xmx1G
set WLS_MEM_ARGS_32BIT=-Xms1G -Xmx1G
)
